while the man page for "objdump" clearly describes the -j/--section option(s)
for dumping a specific object file section, neither of those options are
recognized for the current version of objdump (binutils-2.16.91.0.6-5
).
p.s. those options are also *not* displayed if you just run objdump with no
options or arguments to get its help information. so i'm guessing they don't
really exist anymore, and the man page should just be updated.
